【摘要】 研制成功一种工业用高气压封闭循环二千瓦级连续CO₂激光器,采用多针对平板的电极结构,在气压为90～100托、混合气体比分为CO₂:N₂:He—1:7:20或1:8:20的条件下,在240根钨针阴极与铜板阳极之间形成稳定的辉光放电,其电流方向,气流方向和光轴方向相互之间彼此垂直。对这种激光器的放电特性、输出特性和长时间运转特性进行了研究,本文叙述这种激光器的总体方案、器件组成和工作特性。更多还原

【Abstract】 A high-pressure, sealed-cycle 2 kW CW CO2 laser with pin-to-plste discharge for industrial use has been developed. It uses a multipin-to-plate electro-de structures. The stable glow discharge is produced between 240 pin cathodes and a planar copper anode for 90-100 torr mixture of CO2:N2:He =1:7:20 orl:8:20. In this discharge,current glow,gas glow and theoptical axis are mutually perpendicular. The discharge output power and long-term operation characteristics of the laser ha-ve been investigated. In this paper, the general plan.constitution and operation characteristics has been discribed for the laser.更多还原
